WebbThe phloem lectin PP2 and phloem protein PP1 are found in the phloem of many plants. In situ hybridization shows that the mRNAs encoding these proteins are localized only in companion cells, and immunocyto-chemistry shows localization of the proteins in both companion cells and sieve elements ( Bostwick et al. , 1992; Clark et al. , 1997, … Phloem tissue consists of conducting cells, generally called sieve elements, parenchyma cells, including both specialized companion cells or albuminous cells and unspecialized cells and supportive cells, such as fibres and sclereids. Sieve elements are the type of cell that are responsible for transporting sugars throughout the plant. At maturity they lack a nucleus and have very few organelles, …
WebbPhloem is a living vascular tissue that is found in vascular plants and is responsible for transporting food prepared in the leaves (during photosynthesis) to all the parts of the plant. This whole process of transportation is known as phloem translocation. WebbFigure 7.3. 1: Zone of division. As you move up in the root, the cells begin to get larger, developing into primary tissues.
